[debutant]probleme cast et compilation

Code:

---

1 2 3 4 5 6 7

char file_in[100]; strcpy(file_in, argv[1]); load_block(file_in);   void load_block(char file_name) {

Lorsque je compile mon prog j'ai le droit a ces erreurs

Pourquoi me dit il que c'est arg 1 est un int ?[/code]

integer from pointer without a cast -> tu as oublié l'étoile de load_block

Et je te conseille vivement d'utiliser strncpy au lieu de strcpy...

L'etoile de file_name plutot non?
char *file_name

J'ai essaye :

void *load_block(char file_name);
void load_block(char* file_name);
void *load_block(char* file_name)
mais aucun changement !

Que puis je faire ?

Skyrunner: oui, c'est ce que je voulais dire

Code:

---

void load_block(char* file_name);

Il faut le modifier aussi dans l'en-tête...

J'ai bien mis :

void load_block(char* file_name)

il me repond :
